Around 100 amps and feel for it from there.
Hard to say what "gear" without knowing exactly what machine you are referring to. If an sa200 for example, it will depend on weather you are welding flat or vert or other. On a machine with "gears" you can obtain the same amps at different volts for different applications. I may be wrong, (thought I was once till I found out I was mistaken) but I believe it is high volts for flat and low volts for vertical. I can never remember that till I try it. On a dual control machine the fine adjustment is a percentile of the course setting max. so you can obtain the same amps in more than one "gear".
